SPECIFICATIONS
TERMINAL BLOCK #15
This output becomes active for the overvoltage light (high voltage) or for high
idle control (low voltage) dependent on the setting of jumper J4.
OVER-VOLTAGE INDICATOR
Activates at 14.5 VDC and deactivates at 14.0 VDC.
HIGH IDLE CONTROL
The output will activate when the voltage drops below 12.3 VDC for more
than 1 minute. The output will remain ON for a minimum of 5 minutes
and
until the voltage exceeds 13.0 VDC.
NOTE: This output must only be used in conjunction with the appropriate
safety interlocks for the intended application.
AUXILIARY BATTERY
When an auxiliary battery is present and the system is configured for it, The
System Manager will monitor the auxiliary battery. Output (TB #7) is turned
on when the battery voltage drops below 11.8 VDC for more than 2 minutes.
The output will remain on for a minimum of 5 minutes and until the isolated
battery voltage is greater than 12.5 VDC. If the main battery bank voltage
exceeds 13 VDC, the output will deactivate and the system will then recheck
the isolated battery voltage after a short delay. This allows the system to
become part of a battery separation solenoid system.
NOTE: When configured to monitor a second battery source, only 6 loads
can be controlled as output #7 is utilized for the isolated battery
indicator. All other functions are unchanged.
BATTERY LOW WARNING LIGHT
Output from TB #8 is disabled when the monitored voltage is above 13.2
VDC. Below this level, the output will flash to indicate a voltage drop. The
output will flash at a varying rate proportional to the discharge rate of the
battery. If the system detects a large instantaneous voltage drop, the light will
flash rapidly for 3 seconds and then revert to its current flash rate.
NOTE: The output will remain steady if any load has been controlled off
or the system has been manually reset.
